You can live stream 5.1 surround sound audio onto YouTube to viewers with compatible devices. 5.1 surround sound uses five full bandwidth channels, which include:
- Front left
- Front right
- Surround left
- Surround right
In addition to these five channels, there is one low frequency effects channel designed for a subwoofer.
To stream 5.1 surround sound audio to YouTube Live, you must produce compatible 5.1 surround sound audio content and use a compatible encoder.
Note that only ingestions with mono, stereo and 5.1 surround sound audio are supported. Other audio channel configurations may result in unreliable conversion to stereo.

You can use both RTMP and HLS ingestion protocols to send streams with 5.1 audio. For the system to automatically detect 5.1 surround sound input and produce 5.1 surround sound, you must create stream keys with the “Turn on manual resolution” setting unchecked in Live Control Room.
- Go to Live Control Room by going to YouTube Studio, then click Create Go Live.
